I had a rabbit that did the same thing, and at the same time I had a daughter who was a chronic nailbiter. For her I bought this stuff called Thumz, its in the drugstore where the baby stuff is. It's really for thumbsuckers. it's like a nailpolish but it taste like hot pepper. It stopped the rabbit from chewing the wires and stopped the nailbiter from biting. It was only like 5 bucks, just paint the wires with it where she is chewing, I"m sure the cian (or however you spell it) pepper will not taste good to her.
